ABSTRACT:
This invention relates to a process to polymerize olefins comprising:contacting:(i) propylene and(ii) a mixture comprising, optionally ethylene, and three or more different alpha olefins having 4 to 20 carbon atoms, wherein at least one alpha olefin is present at Z percent or more, based upon the weight of the mixture, where Z=Y+X, where X=(100 divided by the number of alpha olefins present in the mixture) and Y equals 1 to 75, where Z is not more than 95%, with(iii) a metallocene catalyst system.
